' my o. nrrnn; on GossERHILL, PENNSYLVANIA.

I Be it known thatI, RoY G. KEPPLE, a. citi zen oftheUnited States, residing at Gosserhill, in the county of Westmoreland and Stateof Pennsylvania,- have invented certain new and useful Improvements in specification, reference being had to the accompanying drawings.

This inventlon relates to new and useful improvements in dumb bells, and particularly to a dumb bell which is provided with a compressiblegrip on its handle.

An object of-this invention is the provision of a dumb bellwhich is provided with a plurality of flexible springs on the handle thereof, whereby a continuous grip of the handuponthehandle will be necessary to support the dumb bell in a position for use in'eXercise, so that all of the muscles of the fingers, the wrists and" the arms will be.

brought into play when the dumb bell is in use. a

. A still further object of this invention is 25,

the provision of a dumb bell consisting of a handle having heads on its opposite ends,

the handle having collars slidably mounted thereon adjacent its opposite ends, to which the opposite ends of'bowed springsare connected, helical expansion springs being mounted on the handle between the collars and the heads, to normally force thecollars toward each other, to maintain the bowed springs spaced from the handle.

WVith these and other objects in View, my invention consists in the novel construction, combination, be hereinafter more fully described, claimed, and illustrated in the accompanying drawing, in which i Figure 1 is an elevational view of my improved dumb bell showing the ends of the cover of the springs in section; the intermediate portion of the cover being broken away; Fig. 2 is an'elevational view showing the cover in section,"and the springs compressed; Fig. 3 is a sectional view on the line 3-3.ofFig.-1.

Referring more particularly to the draw ing, the dumb bell ,consistsu'of a handle 1 upon the opposite ends of which the heads 2 are detachably connected. I It will be understood that the headsu'may be spherical inform or any other desiredshape, that the same may be connected tothe ends of the red the opposite ends of outwardly of which the following is a the heads" pansion sprlngs 5,,one end of each pand upon outward movement of In the muscles of the and arrangement of parts, to'

handle bythreads, by any other desired Slidably its oppoconnectbowed springs 4 which extend longitudinally of the handle, numben Mounted on the "handle between 2 and the collars 3 are helical exspring being mounted in oneofflthe heads and the other end of the springbeing mounted in the adjacent collar, so that thesprings normally force the collars inwardly and how the springs 4 outwardly in spaced relation from the handle. To inclose the springs 4c and to prevent the same from pinching the hand when the dumb bell is in use, a tubular covering 6 is disposed over the spring, the opposite end edges. of the covering being secured to the periphery of the collars 3, and the covering adjacent its ends being provlded with a plurality of annular crimps 7 therein whereby the cover may readily ex.

the collars when pressure is applied against the springs 4.

practical use of my improved dumb bell, when the handle of the dumb bell is grasped, thecompressible springs 4 move inwardly under the pressure of the hand, until the sameengage the handle, so that a firm grip upon the handle is necessary to hold the dumb bell in a position for use, whereby the fingers, wrists and arms are brought into play. The covering 6 which is of leather or other soft material provides a soft pliable surface to the hand, whereby the springs 4 are prevented from abrading or cutting the skin, and it will be seen that when the springs 4. are forced inwardly without strain upon the covering. WVhen the collars 3 are moved longitudinally upon the handle, the springs 5 are compressed, so that immediately upon release ofthe dumb bell, v the springs 5 assume their normal positions; Under the tension of the springs 5 the collars 3 are moved inwardly upon the handle to; again how the springs 4 outwardly in a position to be grasped when the dumb bell is again desired for use.

"D MB-innit; y 3 a and which are preferably four in tion, what I desire to claim and secure by' I Letters Patent is 1. A dumb bell comprising a handle having heads on its opposite ends, spaced col: lars slidably mounted on the handle, out} wardly bowed springs connected at their opv ,4 'posite ends to said collars, spiral springs mounted on said handle between said heads and said collars, said springs normally forc-.

ing said collars inwardly of the-handle,-and said bowed springs being adapted for movement inwardly against the handle, the inward movement of said bowed springs forcing said collars longitudinally'of the handliagainst the tension of said spiral springs.

2. A dumb bell comprising a handle having heads on its opposite ends, spaced collars slidably mounted upon the handle, outcop'lea of this patent may be obtained for mounted on the handle between said heads and said-collars, and'an expansible tubular covering inclosmg said bowedspringsand.

secured at its opposite end edgesto said collars, said coverl'ng adjacent ts ends having a 'pluralityof annular crimps formed therein Itoallow expansion of the cover, said covering offering a smooth surface intermediate of 1ts ends for engagement by-ahand,whether vsaid collarsra-rein their extended ipositions or normalpositionst r a 1 In testlmonywhereof I hereunto a'ffix my slgnature in the presence of two witnesses.
